METHOD OFY FORMING BUTTON-HOLES.

SPECIFICATION forming part of Letters Patent No. 236,155, dated January4, 188.1.

Application filed August 13l 1879.

useful Im proveinents in Re-enforcement of Button-Holes; and l do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to'make and use the same, reference being had to theaccompanyin g drawings, and to letters of reference marked thereon,which form a part of this specitioation. Y

My invention relates to a new method offorming button-holes in iiexiblefabrics; and it consists, essentially, in interposing between twothicknesses of material, one thickness of which has a key-hole-shapedaperture in it, the button-hole lining or re-enforcement, formed ofcrimped leather andV constructed with a bead surrounding thebutton-slit, the bead serving as a guide whereby to properly locate thecrimped .lining,'hide the cut edges of the key-holeshaped opening, andalso to protect said cut edges from wear, as will be hereinafter fullyexplained.

In the drawings I have illustrated my invention as being applied to thebutton-ily of a shoe, in which drawings- Figure l is a plan view of aportion of a shoe-upper, showing the button-holes. Fig. 2 is an enlargedview of the same, taken on line :c y, Fig. l; and Fig. 3 is a view,detached, of one of the button-hole linings or re-enforcements.

A is the upper, formed of any desired material, such as leather or someof the woven fabrics usually employed for that purpose.

a a, a a are a series of key-hole-shaped openings, formed in the partAin proper position relative to the scalloped edge of the buttontly.

B is the button-Hy lining, of cloth or leather.

C C (l C are the crimped-leather button-hole linings or re-enforcements,such as may be conveniently made upon the machine patented by me June18, 1878. These linings or re-enforcements are each constructed with abead, c, extending in a continuous line around the button-slit c, as isplainly shown in Fig. 3;

.0 Vstitching may be dispensed with without de-y and in applying them Iinterpose thembetween the upper and the lining with the bead projectingthrough or into the key-hole-shaped openings a. After the upper, thelining, and

lthe button-hole linings or re-enforcements have been secured to eachother, I then cutor vpunch a slit, b, in the button-dy lining by meansof a suitable instrument, which is inserted through the button-slit ofthe buttonhole lining or re-enforcement, this slit c serving as a guideto determine the position of the slit in the button lining orre-enforceinent, as will be readily understood.

It will be readily seen that the bead on the button-hole lining servesas a guide to facilitate locating the re-enforcenient in proper positionrelative to the key-hole-shaped opening in the upper or outer material,A, and also serves to hide the edges of the key-hole-shaped opening, andalso protects these edges against being Worn by the contact of thebuttons, which latter feature becomes very important when the part A ismade of cloth.

It will also be seen that, by my method of putti ng these parts togetherand subsequently cutting the button-slits in the button-ily lining bymeans of a cutting-tool introduced through the button-hole lining orre-enforcement, l insure absolute accuracy in the location of thebutton-slits b.

I usually secure the parts together by means of some adhesive material,and also by a rovir ofstitching extending around'outside the bead buteither the adhesive material or the parting from the spirit of myinvention.

l am aware that I am not the first to interpose a tough inelasticre-enforcement between the upper and the lining of a button-ily; but assuch device had been employed prior to the date of my invention itconsisted of a thin piece of leather, dat upon both sides andimperforate, for which reason it is apparent that it contained nothingcorrespon ding to my combination of the button-hole lining G, having thebead c' and slit c, with a button-hole provided with a key-hole shapedopening, a. Hence it was impossible that in such earlier constructionsthe position of the button-slit in the lining B relative to thekey-hole-shaped ICQ opening a could be determined by the position of thebutton-hole re-euioreelnent, the posicion of which, in turn, isdetermined by the bead 0.

Vhat I claim is- The herein-described method of makinghutton-holes-that; is to say, by interposing a button-hole lining orre-enforcelnent, C, having :L bead, 0, and button-slit o', between anupper, A, having a keyhole-shaped opening, a, there- 1o in, and animperforate lining, B, the bead heing inserted in the opening a, andafterward making :L button-slit in the lining B opposite the slit c',substantially as set forth.

1n testimony that I claim the foregoing as my own I aix my signature inpresence of 15 nwo witnesses.
